I need to do something like this:
do shell script "openssl sha1
a2d3b4c5a2d3b4c5fa2d3b4c5fa...5fa2d3b4c5fa2d3b4c5fa2d3b4c5fa2d3b4c5ff
openssl sha1 expects a filepath. If not, just a return, it will process standard input until ^D.
As above doesn’t work.
Now what?
set mydata to "rtyeylohyvuftydyrerussy"
do shell script "echo \"" & mydata & "\"| openssl sha1"
Good grief!
Hello there.
Try this in a terminal window:
echo |openssl sha1What is going on here, is that the echo command (man echo sends a newline through the |.
So hopefully this will work for you:
do shell script "echo |openssl sha1
a2d3b4c5a2d3b4c5fa2d3b4c5fa...5fa2d3b4c5fa2d3b4c5fa2d3b4c5fa2d3b4c5ff"
And you do use my applet/droplet for opening terminal windows in tabs don’t you? 
A | is named a pipe and connects stdout of the left command to the stdin of the right command of the pipe.
As you have may have noticed in some/many of my example code I use:
do shell script "/bin/echo -n hello world"
That is not the shell’s built in echo command which has a few options more than the buil-in version. With the option -n you tell echo not to print a traling newline.
Because openssl likes to read from stdin, which is not that uncommond for command line utilities, you should use
set mydata to "rtyeylohyvuftydyrerussy"
do shell script "/bin/echo -n " & quoted form of mydata & "| openssl sha1"
I know what a pipe is. And stdin. And stdout. What I have trouble is with right and left. :lol:
I hate the <expletive deleted> terminal!
Well, It is a great place for figuring out how your “do shell scripts” works!
And we all have to resort to that sooner or later. you can just drop a folder on my droplet to go to that folder!
if you move arrow up you should go to the last command, history |more gives you an overview of previously entered commands.
It is not so dreaded, once you get used to it.
